Application filed February 10, 1914. Serial No. 817,829.

To all, whom it may concern Be it known that I, JOHN SLATTERY, a citizen of the United States, and a resident of Chro'ine, in the county of Middlesex and State of New Jersey, have invented a new and Improved. Car-Wheel, of which the following is a full, clear, and exact description.

This invention relates to -improvements in.

car wheel construction, and has for an object to provide an improved wheel structure wherein a solid center is presented and a wearing rim connected with the periphery thereof-- Another object of the invention is to provide an improved wheel in which is presented an improved locking member for the wearing rim or tire, whereby the parts are rigidly connected together.

In carrying out the object of 'the invention a centeror bodyis provided in any desired manner, and is formed with flanges extendingtherefrom, which flan es are adapted to be inte'rlockedwith suitable grooves in a-tire or wearing band. The tire or wearing band is provided withannular notches and an annular groove merging into said notches, which coves and notches receive the om the center or body. In mounting the rim in place one of the flanges of the center or bod is arranged radially so asto properly fit the rim or tire, and the other is arranged parallel with the-axis of the body and then rolled or bent over and pressedinto the notches and grooves of the tire. A plurality of;.lugs are arranged in the body and fitted 'intogrooves inthetire so as to ,posi

tively prevent any sliding of one member in respectto the other. r a; v

In the accompanying drawingsFigure 1 isa side'view of a wheel disclosing an eming broken away; Fig. 2 is a section through Fig. -1 approximately online 2+2; Fig-3 is a 'sectional-view-similarto Fig. 2 except that the parts have been'properly fitted in place;

Fig. 4 is a fragmentary sectional view through the tire on shoe of the wheel; Fi

5 is'a fra mentary sectional view throng and 2 the t re or shoe.

part of the body of the wheel.

Referring to the. accompagymgdrawings by numerah-l indicates the b y of the wheel In forn'nn car wheels it is desired to make the b0 y 1 and shoe 2 out of diflerent grades of material. For instance,-the shoe 2 is made out of a high grade material, while the body 1 is made out of a comparatively low grade of material. This reduces the expensc of the manufacture of the wheels, but

allows a high grade-traction surface to be g,

presented to the rails. In the formation of the shoe or tire 2 the periphery is made in the s ual manner, and in fact the entire rim is rolled so as to be of the right size, and in the rolling notches 3 and 4 are provided, which merge into grooves 5 and 6. In manufacturing the body 1, which maybe of any desired material, but preferably of alow grade ofmaterial, the flanges 7 and 8 are rolled so that one flange will extend radially 7 and the ether axially. I In the drawing, flange 7 1 "shown as the radial flange which fits into notch 3 while the bead 9 fits into groove 5. The flange 8 as shown in Fig. 2 does not fit into the notch 4: until after the 7 shoe 2 has been placed in position. After shoe 2 has been placed in position the flange 8 is bent over and forced-into position, as '.f

shown inFig. 3. The parts ina be hot when .9

this is done or the flange ma e rolled in a cold state. In forming the ead 9 and the ormed by rolling orb being. turned} in a lathe, and also the shoe 2 may be finished in a'lathe so that the arts will accurately fitias when assembled. {T 1e flange 8 is 'IOVldQd" with extra material which is onit e: inner surface when the flange is in the position shown in Fig. 2', but is forced into'the body of the flange while some ofthe bodyof the 9 flange is'forced into groove 6 forproviding the V-sh'aped bead 9 shown in F g. 3: By this means the body is provided with/radial flanges. fitting .into the notches 3Q/"and 4. When forming the shoe 2 the same is pro- 9 vided with a plurality of transversenotches or grooves 10 which receive the! lugs 11, whereby the shoe 2 is preventedypositively, any rotation independent of bod 1. The lug 11 may be a projection from ody 1, or a suitable keyway ma be provided in body 1 and a key inserted t ereinwhich will connect the body 1 and shoe 2,,thus acting as a double key. As shown in Fig; 3, when the wheel 'iscompletedthe flanges 7 and 8 are arranged in the notches 3 and 4, while .the beads 9 and '9" are arranged in the groove 5 and 6,- thus locking by a form of dovetail the Y shoe and thebody otthe wheel. Ordinarily, when the parts are" assembled, as shown in- Fig. 3, the pinching action of the tparts will be suflicient for properly holding t e shoe in eriphery of the body- 1 the same may be place, but the lugs or keys 11 will positively prevent any independent movement of either of the members-1 or 2.

What I claim isi 'In a wheel of the character described, a shoe provided with an internal annular flange,the sides of said flange being offset inwardly from the'sides of the shoe and formed on the sides with V-shaped grooves, a body arranged in said shoe provided with a peripheral bearing surface fitting against the inner surface of said flange, a radial flange having a V-shaped bead extending normal thereto for fitting into one of the 15 grooves in said annular flange, and a. hori zontally extending bendable flange, said bendable flangebeing adapted to be forced over for preventing a rotation of the shoe independent of the body.

In testimony whereof I have signed my I name to this specification in the presence of two subscribing witnesses.
